    Musical Fidelity V-LINK USB SPDIF

    Hi there,   Just got a V-Link II and plugged it into a PC running Ubuntu. The USB signal doesn't lock (actually it does for a few seconds when I turn on the computer - the green light appears - then stops). The command cat /proc/asound/VLink/stream0 returns:   Musical Fidelity Musical...

    Bit Perfect Audio from Linux

    Well, no, in  Switzerland. Here the Vlink 192 cost almost double!! But anyway I need the Vlink-II since the DAC won't accept more than 96kHz anyway, and this one is cheaper (I will then have a trouble playing 192k files then! More headaches to come! ) ... or the M2Tech, that's an option too.  ...

    "Supported audio sample rates include 48 kHz, 44.1 kHz..."   .... Still don't understand why it does not convert 44.1 properly then ...   but I guess it isn't worth trying to work that out ...  ... let's use the usb instead

    Quote:   Right. Make sense. So two options left: a newer PC, or a USB2SPDIF device, I guess.   Thanks and congratulation for working this out!   Jerome

    Deadbeef, yes. Chip in AlsaMixer v1.0.25 is SigmaTel STAC9750,51  and the card is Intel 82801DB-ICH4

    Quote:       Good pick! I have two S/PDIF bargraphs: - one "S/PDIF" stuck to 00 no matter what - one "S/PDIF Playback AC97-SPSA" which can take 4 values: 00, 33, 67 and 100. It was on 67. But there a signal only at 100. Don't know why.   Now I have an output on "...-IEC598...

    Bit Perfect Audio from Linux

    Bouhouhou!!!   (doesn't work!)   I managed to kill pulse audio, though. Good start. And when I play "vlc --alsa-audio-device=hw:0,4 -I qt4 -d" as Anda suggested, I do not get the "device or resource busy" as before ... ... and apparently there is a signal (at 48kHz though, see below)...

    Bit Perfect Audio from Linux

    Good morning,   Trying to play with VLC works on the default output option (trough pulse audio), but when I try to use the option IEC958 - without any conversion, I get an error message:   Audio output failed: The audio device "hw:CARD=I82801DBICH4,DEV=4" could not be used: Device or...

    To Kim, Yes, I can see a similar list with aplay -L (thanks by the way to point to the case sensitive behaviour), or even in the Preference/sound/Output device box directly in DeadBeeF. The thing is that i doesn't exit any sound except when I put the option mentioning explicitly S/PDIF (in...

    Bit Perfect Audio from Linux

    Hi again,   To Anda: it returns about 9 pages of parameters. What should I be looking for? Most parameters concern video and other stuff. The ones which I can figure are around audio are:       ...   udev Discs udev Audio capture (ALSA) ...     mtp MTP devices mtp MTP...

    Well, I can downsample to 48kHz but only with the resampler Secret Rabbit Code installed in the DSP tab of the Preferences pannel. If I remove it, as you suggested earlier, it doesn't work properly. The same wiht 44.1: it only works with a rabbit nearby, which completely defeat the "bit perfect"...

    Bit Perfect Audio from Linux

    Hi Kim,   Well, actually, I cannot use the option "Direct Hardware without any convertion", because in that case the output is not directed to the spdif (no sound). I use instead "IEC958 (s/pdif) Digital Audio Output".   The interesting thing is that in the file hw_params, I see rate...

    Bit Perfect Audio from Linux

    Hi guys,   Thanks for all the tips, I have done great progress... but I still have the same trouble than Gustmahler in reply 59: if I disable DSP, my 96kHz files are played at 48kHz speed, i.e. twice slower and twice deeper (using DeadBeef and Ubuntu 12.04 on a (very) old DELL Inspiron 8600...
